Symposium Scope/Topics
Atom Probe Tomography (APT) has emerged as a transformative tool in materials science, enabling 3D compositional imaging at near-atomic resolution with part-per-million sensitivity. This symposium aims to spotlight the most recent advances and applications of APT in uncovering the nanostructure–property–performance relationship across a wide range of materials systems. The focus will be on using APT to unravel nanoscale features such as chemical short range order, solute clustering, segregation, precipitation, phase transformations, interfacial phenomena, and defect structures, all of which are central to understanding materials behavior under extreme environments, degradation, and failure.
This symposium will bring together researchers and industry practitioners employing APT in conjunction with complementary characterization tools (e.g., TEM, TKD) and computational modeling (e.g., phase-field, DFT, MD) to tackle challenges in microelectronics, metallurgy, energy materials, and additive manufacturing. Special emphasis will be given to correlative studies and technique development, including cryo-APT, site-specific lift-out, in situ approaches, and machine learning-assisted analysis
The session will serve as a dynamic platform for discussing critical insights into materials degradation and failure mechanisms, advancing our understanding of atomistic processes governing reliability and performance. We welcome contributions that cover fundamental studies, novel methodologies, and application-driven research, with the ultimate goal of advancing materials design and failure prevention at the nanoscale.
Topics will include:
- Advanced applications of APT in metallurgy, semiconductors, and energy materials
- Solute segregation, clustering, chemical short range order, and phase transformations
- APT of interfaces, dislocations, grain boundaries, and other defects
- Cryogenic and in situ APT techniques
- Correlative APT-TEM/TKD studies
- Atomistic insights into failure mechanisms and degradation
- Machine learning and data mining in APT analysis
- Multiscale modeling and APT-informed simulations
- Challenges in quantification and specimen preparation
